To all whom/it may concern.-

Be it known that I, GEORGEB. FRALEna citizen of the United States,residing in the city and county of Philadelphia,State of Penn--sylvania, have invented anew-and useful Im-' provement in Apparatus forProducing Motive Power from Liquid Gas, of which the followingis aspecification. My invention consists of an improved construction of anapparatus for producing motive power from liquid'gas,wherein I employsuitable means to gasify the liquid gas and raise the temperature of thesame, so that the liability of freezing is prevented, the gas beingtransformed, so that it can be safely and economically used ina'su'itable motor,where-- from the energy for the motive power isderived.

It further consists of novel details of construction, all as will behereinafter fully described, and particularly pointed out in the claims.

The figure represents a side elevation, partly in section, of anapparatus for producing motive power from liquid gas embodying myinvention, showing especially the regulating device and the means forraising the temperature of the liquid gas employed.

In the drawings, 1 designates a tank for the reception of the liquid gasemployed, the outlet-pipe 2 therefrom being controlled by the valve 3,said pipe leading into the casing 4, which forms a hot-water tank. Thepipe 2 after entering the hot-water tank takes the form of the coil 5,which I term a gasifyingcoil, which latter after leaving the tank 4--means of the pipe 13.

14 designates the base which supports the chamber and jacket, said basehaving located therein the heating device 15, which discharges into thecombustion-chamber 16,while aportion of the heat enters the chamber 10through the ports 17.v

18 designates a plunger which is adapted ably packed by means of thepacking 19 and the gland 20.

to reciprocate in the chamber 7 and is suit-V1,

21 designates weightswhioh are removably supported upon the plunger18,the latter having the arm 22 projecting therefrom,which is providedwith the slot 23, through which passes one end of the lever 24,whichlatter is fulcrumed at the point 25 and pivotally attached to one end ofthe link 26, the other end of the latter being pivoted to the lever 27which is fulcrumed at the point 28.

29 designates a link having one end pivot ally attached tothe lever 27,while the other end of said link is connected to the arm 30,

which actuates the valve 31, whereby it will be seen that as the volumein, the chamber 7 varies the plunger 18 will be raised and low;

ered, which movements will automatically control the supply of liquidgas to the gasify;, ing-coil 5, which is in communicationwith eliminatesthe freezing difficulty and at the 'same time reduces the gas into aneconomical and safe working pressure, as said liquid gas becomesgasified in its passage from the coil 5, its temperature beingsimultaneously raised, and by passing it to the regulator, as abovedescribed, the latter will act as a superheater, and the plunger orpiston 18 causes an even pressure to be maintained at all times. 7 Thegas having been reduced to proper rworking 5 temperature is nowwithdrawn from the in the manner described can be readily utilized inmotors of various constructions, and I do not desire to be limited toany particular construction of a motor, and it will also be apparentthat the liquid gas can be acted upon in other forms of apparatus thanthat shown and described herein without departing from the spirit of myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an apparatus for producing motive power from liquid gas, means forraising the temperature of the liquid gas, a regulating deviceconstructed and arranged to serve as a superheater, and means forconducting said gas after its reduction to a safe working pres sure toany suitable point.

2. In an apparatus for producing motive power from liquid gas, aregulating device through which said gas passes,said regulatorconstructed and arranged to serve also as a superheater, means actuatedby said regulatin device for regulating the flow of said liquid gas, andmeans for conducting the latter from said pressure-regulator to asuitable point.

3. In an apparatus for producing motive power from liquid gas, agasifying-coil for enabling the temperature of a liquid gas to beraised, a chamber in which said gasifyingcoil is confined, a regulatingdevice constructed to serve also as a superheater, and means operated bysaid regulating device for regulating the flow of said liquid gas tosaid gasifying-coil.

4. In an apparatus for producing motive power from liquid gas, aliquid-gas receptacle, a gasifying device connected therewith, awater-tank and means for maintaining a circulation of water therein, andmeans for antomatically controlling the supply of gas from saidreceptacle, said means being controlled by the volume of gas produced bysaid circulating means.

5. In an apparatus for producing motive power from liquid gas, means forraising the temperature of the liquid gas, means for regulating thesupply of said gas to said temperature-raising means automatically, andmeans for heating said regulating device.

, 6. In an apparatus for producing motive power from liquid gas, meansfor raising the temperature of the liquid gas, means for converting thesame to a safe working pressure, said means constituting a regulatingdevice, means embodied in said regulating device for controlling thesupply of said liquid gas, a heating-chamber surrounding said regulatingdevice, and heating means for said chamber.

7. In an apparatus for producing motive power from liquid gas, a sourceof supply for the liquid gas, a tank containing a gasifyingcoil, a pipefrom said source of supply to said coil, a valve in said pipe,connection leading from said tank to a heating device, a plungercontained within said heating device, and a pipe leading from saidgasifying-coil to the space below said plunger.

8. In an apparatus forproducing motive power from liquid gas, a sourceof supply for the liquid gas, a tank containing a gasifyingcoil, a pipefrom said source of supply to said coil, a valve in said pipe,connections leading from said tank to a heating device, a plungercontained within said heating device, and a pipe leading from saidgasifying-coil to the space below said plunger, in combination withactuating mechanism common to said plunger and valve.

9. The combination of a tank for liquid gas, a valved outlet-pipeleading therefrom, a hotwater tank, a gasifying-coil located therein, aregulating device into which said coil discharges, a heating device forsaid regulating device, a jacket surrounding said regulating device, andcontaining a hot-Water coil, connections from said hot-Water coil to andfrom said hot-water tank, a plunger located in said regulator, andconnections common to said plunger and valve.

10. In an apparatus for producing motive power from liquid gas, a tankcontaining a liquid gas, a hot-Water tank, a gasifying-coil in saidhot-water tank, a valved pipe leading from said gasifying-coil to saidgas-tank, a regulating device, into which said coil discharges, aplunger in said regulating device, connections from said plunger to saidvalve, a hot-air chamber surrounding said regulating device, and a coillocated in said hot-air chamber and having connections to and from saidhot-water tank.
